[PATCH 18/21] drm/i915: Start exploiting drm_device subclassing

Mon May 30 22:39:26 UTC 2016


Baby step, update to_i915() conversion from drm_device to
drm_i915_private:

   text	   data	    bss	    dec	    hex	filename
1108812	  23207	    416	1132435	 114793	i915.ko (before)
1104999	  23207	    416	1128622	 1138ae	i915.ko (after)
